## Detailed Description

This is a helper for listening to and accepting D-Bus connections.

Since Server derives from Initiable, its constructors can throw an exception if construction fails.

This can be used to create a new D-Bus server, allowing two peers to use the D-Bus protocol for their own specialized communication. A server instance provided in this way will not perform message routing or implement the org.freedesktop.DBus interface.

To just export an object on a well-known name on a message bus, such as the session or system bus, you should instead use Gio::DBus::own_name().

## Member Function Documentation

static Glib::RefPtr<Server> Gio::DBus::Server::create_sync | ( | const std::string & | address,
|  | const std::string & | guid,
|  | const Glib::RefPtr< AuthObserver >& | observer,
|  | const Glib::RefPtr< Cancellable >& | cancellable,

| ) |  | `[static]`

Creates a new D-Bus server that listens on the first address in address that works.

Once constructed, you can use g_dbus_server_get_client_address() to get a D-Bus address string that clients can use to connect.

Connect to the DBusServer::new-connection signal to handle incoming connections.

The returned DBusServer isn't active - you have to start it with g_dbus_server_start().

See <xref linkend="gdbus-peer-to-peer"> for how DBusServer can be used.

This is a synchronous failable constructor. See Glib::dbus_server_new() for the asynchronous version.

Since glibmm 2.26:

Parameters:

  address | A D-Bus address.
  flags | Flags from the DBusServerFlags enumeration.
  guid | A D-Bus GUID.
  observer | A DBusAuthObserver or `0`.
  cancellable | A Cancellable or `0`.

Returns:
  A DBusServer or `0` if error is set. Free with Glib::object_unref().

Exceptions:

  Glib::Error. |

Glib::SignalProxy1< bool,const Glib::RefPtr<Connection>& > Gio::DBus::Server::signal_new_connection | ( |  | ) |

Emitted when a new authenticated connection has been made.

Use Gio::DBus::Connection::get_peer_credentials() to figure out what identity (if any), was authenticated.

If you want to accept the connection, keep a global reference to the connection (by keeping it in a global RefPtr<>) and return `true`. When you are done with the connection call Gio::DBus::Connection::close(). Note that the other peer may disconnect at any time - a typical thing to do when accepting a connection is to listen to the Gio::DBus::Connection::signal_closed() signal.

If property_flags() contains Gio::DBus::SERVER_FLAGS_RUN_IN_THREAD then the signal is emitted in a new thread dedicated to the connection. Otherwise the signal is emitted in the thread-default main loop of the thread that server was constructed in.

You are guaranteed that signal handlers for this signal runs before incoming messages on the connection are processed. This means that it's suitable to call Gio::DBus::Connection::register_object() or similar from the signal handler.

Prototype:
  `bool on_my_new_connection(const Glib::RefPtr<Connection>& connection)`

void Gio::DBus::Server::start | ( |  | ) |

Starts server.

Since glibmm 2.26:

void Gio::DBus::Server::stop | ( |  | ) |

Stops server.
